Global Light and rasterizing effects

…In this movie, we'll take a look at the inner workings of Global Light.…And I'll show you how to rasterize your layer effects,…that is convert them to pixels so you can edit them with other tools.…Global Light is that unifying force that insures that you…have a consistent lighting angle inside of your image.…And it applies to the three directional layer effects, which are Drop Shadow,…Inner Shadow, Embevel and Emboss.…And it's a function of two options, angle and altitude.…Now there's only one layer effect that gives you access to both of those options,…and that's bevel and emboss.…So I'm going to go ahead and expand the Spider's layer, and…double-click on bevel and emboss in order to open the layer style dialogue box.…And you can see that Use Global Light is turned on so…this effect is part of the Global Light System.…

And so are the other directional effects inside of this image including by the way,…the Inner Shadow and Drop Shadow effects that are assigned to this layer.…Both of them have use Global Light turned on.…
